Managing Docker with Puppet

Docker is a platform for rapid deployment of containers. Containers are like a lightweight virtual machine that might only run a single process. The containers in Docker are called docks and are configured with files called Dockerfiles. Puppet can be used to configure a node to not only run Docker but also configure and start several docks. You can then use Puppet to ensure that your docks are running and are consistently configured.

Getting ready

Download and install the Puppet Docker module from the Forge (https://forge.puppetlabs.com/garethr/docker):
